Consistently enjoyable - I keep coming back to it.
Awesome works great
STUNNING!!! OH WOW! This app puts every other similar app I have tried to shame! Rarely are you so blown away by an app that you remain mesmerized and captured by it...aside from addictive games....THIS APP DOES THAT, AND TEACHES AT THE SAME TIME. My new favorite app of all time!
Good job, Vortex! Thanks to Vortex, I'll never know sleep, again! Though my head and phone may be permanently aimed at the night sky, my neck may be permanently cricked and my eyes may be bloodshot from staying up all night, dang, is this cool! What a time to be an amateur astronomer!
Great app It is very useful in teaching astronomy( for an older version june 2013). Since I am asked to rate it again, then it would be the same 5 stars. It just keep on improving ( as it is supposed to be) for a smoother experience. Keep up the good work guys. Sept 17, 2015.
Doesn't work Content is good, but it doesn't actually display what is in front of the phone. You have to look around by scrolling.
